Approximate Analysis of Intersecting Equal Diameter Cylindrical Shells Under Internal Pressure

Abstract

Stresses in the vicinity of the crotch of a pressurized, crossed cylinder pipe connection and a tee connection with equal diameter and thickness branches are determined by two different methods. In the first the structure is reduced to an equivalent, axisymmetric shell, while in the second, ovaling deformations are taken into account. The results agree well with each other and with published experimental results.
